2 Claims.

The present invention, which is a division of my application, Serial No.30,374, filed July 8, 1935, relates to road guards. For a completeunderstanding of the invention, reference is made to the followingdescription, the accompanying drawing and the appended claims.

In the drawing: 7

Figure 1 is a front elevation of a' road guard embodying the presentinvention;

Figure 2' is a plan view of the end of a road guard;

Figure 3 is a plan view of an alternative embodiment of the invention;

Figures 4 and 5 are plan views, respectively, of further alternativeembodiments of the invention; and i Figure 6 is a top view of aconstruction which may be used in connection with road guards.

Referring more particularly to the drawing, as disclosed in the parentapplication, the invention relates to a road guard which includes aseries of upstanding posts A suitably mounted in the ground. These postscarry brackets B having suitable slots C formed therein for positioninga plurality of flexible elements 99 which are held formed into a loopwith its ends in overlapped in the slots by retainers E. The flexibleelements 99 may take the form of wire rope or cable. The presentinvention relates particularly to theend anchorage means for flexibleguard rail elements.

Figure 2 illustrates a post 96 to which a piece of fiat spring metal 91is circumferentially fastened by means of a bolt 98. This piece .91 isrelationship and the bolt 98 fastens this piece so as to permit relativemovement of these overlappedends. A wire rope 99 terminates at the post96 and is arranged around the piece 91 in collapsing relationship. Inother words, this wire rope is wrapped around the, piece 91 so that theapplication of various tensions to the rope will cause the loop tocollapse various amounts. This particular construction may constituteone of the ends of a complete road guard, the loop then functioning totension the wire rope 99, the, latter then functioning as a guardrail.

Figure 3 shows the same construction as that of Figure 2, similarnumbers being therefore used However, it is to be noted that in Figure 2the end of the wire rope 99 is looped back onto itself and fastened by aclamp I00, whereas inFigure 3 this end is fastened to the post 96 bymeans of a hook-ended bolt IIlI that is passed through the post atright-angles to the bolt 98.

Figure 4 shows a post I02 to which a piece of fiat spring metal I03 istransversely fixed by means of abolt I I3, this arrangement being sim-10 ilar to that illustrated by Figure 2 excepting that the piece I I2 ispierced at opposite points by the bolt I I3. A wire rope I I4 is wrappedaround this piece II2, the difference between this andthe otherconstructions of a similar nature which have been disclosed being thatthe rope is passed between the spring loop and the post so that the boltH3 is under tension.

Figure 6 illustrates a post I0! to which an endless loop of flat metalI98 is transversely fas- H tened by means of a bolt I09 which passescompletely therethrough. A wire rope H0 is wrapped around this loop I08in the same manner as was the case in the construction illustrated byFigure 2.

It is to be understood that all of the constructions illustrated areprimarily intended to be used at the ends of a road guard for thepurpose of tensioning or mounting the guard rail. Furthermore, that mostof the various constructions which have been disclosed arecharacterizedby including a piece of flat spring metal strip that istransversely fastened to a post in such manner that relative movement ofthe ends of this strip is permitted. This enables the various forms ofloops to collapse more readily when absorbing shocks.

I claim: I l. A road guard including the combination of a post, a pieceof fiat spring metal formed into a loop and with its ends arranged freeso as to permit relative movement of the same, said loop being mountedby said post so as to permit said relative movement, and a guard railterminating at said post and arranged aroundsaid loop in collapsingrelationship.

2. A road guard including the combination of a post, a piece of flatspring metal formed into a loop with its ends in overlappedrelationship, means for fastening said loop transversely to said post soas to permit relative movement of said overlapped ends, and a guard railterminating at said post and arranged around said loop in collapsingrelationship.
